Things are getting a little bit hairy on Nickelodeon. Victoria Justice, star of the #1 Nickelodeon show "Victorious," is playing a she-wolf in the upcoming television movie, "The Boy Who Cried Werewolf."

Justice, in her first headlining TV movie role, stars as Jordan, an unpopular, allergy-prone teen who sees her family inherit her Great Uncle's castle in Wolfsberg, Romania. After a freak lab accident, Jordan begins transforming into a werewolf, and, like other teen wolf movies, suddenly becomes more self-confident. Of course, there's a dangerous side to her new personality.

"The Boy Who Cried Werewolf" also stars Brooke Shields, as Madame Varcolac, the Romanian housekeeper who currently cares for Vucovic's ancient castle and knows plenty of its secrets. The movie also stars Matt Winston ("StarStruck"), Brooke D'Orsay ("Drop Dead Diva"), Steven Grayhm ("The Family Tree"), and Chase Ellison ("Tooth Fairy").

"Our audience will love seeing Victoria in this new role as shrinking-violet-turned-werewolf," said Marjorie Cohn, President, Original Programming and Development, Nickelodeon. "And Brooke Shields' turn as the hilariously sinister Madame Varcolac is a wonderful homage to 'Young Frankenstein''s infamous Frau Blucher. This movie blends mystery, suspense and comedy and serves up a perfect Halloween viewing experience for kids and their parents."

Of course the movie airs on Nickelodeon just in time for Halloween. "The Boy Who Cried Werewolf" premieres Saturday, October 23rd at 8pm ET/PT.
